We emit an `info!` log for every peer that we discover but only ever
emitted a `debug!` log if we fail to connect. This leads to a situation
where the user would run `swap list-sellers`, the logs would say
"Discovered XYZ at ABC" but then get a potentially empty table.
To not confuse the user, we include unreachable nodes in the table output.
For example:
```
Connected to rendezvous point, discovering nodes in 'xmr-btc-swap-testnet' namespace ...
Discovered peer 12D3KooWPZ69DRp4wbGB3wJsxxsg1XW1EVZ2evtVwcARCF3a1nrx at /dns4/ac4hgzmsmekwekjbdl77brufqqbylddugzze4tel6qsnlympgmr46iid.onion/tcp/8765

| ??? | ??? | ??? | Unreachable | /dns4/ac4hgzmsmekwekjbdl77brufqqbylddugzze4tel6qsnlympgmr46iid.onion/tcp/8765/p2p/12D3KooWPZ69DRp4wbGB3wJsxxsg1XW1EVZ2evtVwcARCF3a1nrx |

This command uses a rendezvous node to find sellers (i.e. ASBs) and query them for quotes.
Sellers, that can be dialed and queried for a quote will be listed.
Some network and application specific code does not belong in the protocol module and was moved.
Eventloop, recovery and the outside behaviour were moved to the respective application module because they are application specific.
The `swap_setup` was moved into the network module because upon change both sides will have to be changed and should thus stay close together.
Instead of splitting up the transports into capabilities, we compose
them directly for each application. This allows us to remove the
websocket transport for the CLI which is really only needed for the
ASB to allow retrieval of quotes via the browser.
EnvFilter is applied globally. This means you cannot log at INFO level
to the terminal and at DEBUG level to log files. To get a around this
limitation I had to implement the layer trait on a new type and filter
in the on_event() trait method. Each swap has its own log file denoted
by its swap_id. The logger appends to the existing file when resuming a
swap.
Closes#278
The CLI has sensible default values for all parameters,
thus a config file is not really an advantage but just
keeps getting in our way, so re remove it.
Rust fmt automatically groups the imports (from top to bottom) as `pub use` `use crate` and `use`.
There is no need to introduce sections which cause annoyance when auto importing using the IDE.
This includes the introduction of the --data-dir parameter instead of the --database.
Both the seed file and the database are stored in the data-dir, the database in sub-folder `database`.
Created network, storage and protocol modules. Organised
files into the modules where the belong.
xmr_btc crate moved into isolated modulein swap crate.
Remove the xmr_btc module and integrate into swap crate.
Consolidate message related code
Reorganise imports
Remove unused parent Message enum
Remove unused parent State enum
Remove unused dependencies from Cargo.toml
As Bob is dialing Alice, we now ensure that we are connected to Alice
at each step that needs communication.
If we are not connected, we proceed with dialing.
In an attempt to improve libp2p usage, we also add known address of
Alice first and only use peer_id to dial.
This ensures that we use the expected peer id.
The numerous tor conditional compile flags were removed by
extracting transport creation to the main statement. A tor
transport is created if Alice specifies a tor port using the CLI.
The hardcoded configuration was replaced with CLI
configuration options. CLI based config was chosen
over a config file as it does not access and clutter
the user's file system. By CLI options depend on whether
the program is run in Alice or Bob mode.
Add a binary crate `swap` that implements two nodes (Alice and Bob). With this
applied we can start up a node for each role and do:
- Bob: Requests current amounts using BTC is input
- Alice: Responds with amounts
- Bob: (mock) get user input to Ok the amounts
... continue with swap (TODO)
